It's become language of legend around the world - "May the force be with you."
Using the hashtag MayThe4thBeWithYou it's the perfect time to rejoice on Twitter and show appreciation for the saga.
The holiday status of the date has been an inside joke for years amongst fans of the sci-fi universe created by George Lucas.
The unofficial Star Wars Day is now being used by marketers who are taking advantage of the "holiday" with giveaways, sales and other promotions.
Fans from all over the world pull on their favorite Obi Wan, Luke Skywalker and/or Darth Vader costumes to celebrate the day.
If the Ukraine had only let Darth Vader run in the upcoming elections on May 25th, the day could be doubly interesting.
No matter what happens in this Universe - Star Wars fans know that good does win out over evil in George's saga.
So, may the 4th be with you, wherever you are in the world today, and at the risk of incurring the wrath of a certain section of Star Wars fans, also "live long and prosper."
